datastore questions

[KevinM]

I am partway through writing an attachment hack, but I have got stuck on something probably (hopefully) quite simple.

I need to access details in the datastore, but I can't seem to find the correct terms.

The info I wish to use in my page is

PHP Code:

$attachtypes = unserialize($datastore['attachmentcache']); 


but I am unsure as to what statements preceed this to allow this to work. E.g. I have tried

PHP Code:

$specialtemplates = array( 
'attachmentcache'     
); 


without success. I've tried including global.php as well.

All help appreciated.
